Data Validation

Heliconia Demographic Survey Data

We use the R package pointblank to review and validate the plot-level descriptors (HDP_plots.csv) and clean demographic data set (heliconia_survey_clean.csv) in preparation for archiving in Dryad and publication in Bruna et al. (2023). The report below includes:

the different validation tests that were conducted,
the date of the most recent test,
each test’s criteria for ‘pass’, ‘warn’ and ‘stop’,
the number of ‘units’ (i.e., rows or columns) assessed in each test,
how many of these units passed or failed, and
a button for downloading a .csv file of the records flagged by a particular validation test. Note that these are not necessarily errors. For instance, the validation procedure for ‘plant size - height’ returns as ‘stop’ all plants >2 m tall. Heliconia plants can exceed this threshold; this test is simply designed to flag any such individuals. In contrast, the data set should not have any duplicated rows. A notification of ‘fail’ for this test indicates an error that can be corrected by downloading the csv file, reviewing the duplicated rows, and uploading the necessary corrections.

Zombie plants

Zombie plants are those that were recorded as ‘Dead’ in a survey but for which there is a measurement in a subsequent year (indicative of the plant losing all below-ground parts and then new shoots emerging prior to the next survey). This validation generates a .csv of any plants meeting this condition (labeled as ’zombie` for review and correction.

Plant Mortality: Plant size

Tests for plants 6 or more shoots dying from one year to the next. Note: These are not errors, these are plants whose size the year prior to being recorded as ‘dead’ in a survey was in the top 2% of dying plants.

Test criteria: ‘warn’ if \(\geq\) 1 rows fail conditions, ‘stop’ if \(\geq\) 2% of rows fail conditions.
